A conductive terminal structure for a piezoelectric device used as part of a tire mountable apparatus is provided. Unlike known electrical connection structures which include a plurality of conductive terminals that are all exposed through a single insulating layer of the piezoelectric device, such as a top layer of the piezoelectric device, the electrical connection structure can be arranged in a one up, one down configuration. In this configuration, at least one conductive terminal is exposed through a top insulating layer of the piezoelectric device. In addition, at least one conductive terminal of a piezoelectric component is exposed through a bottom insulating layer of the piezoelectric device. The electrical connection structure can be used in combination with a connector assembly design to preserve the integrity of the electrical connection between the electrical and mechanical connection structure and a printed circuit board.

One up, one down connection structure for piezoelectric device in tire patch

Disclosed is a tire mountable apparatus and method that includes a substrate defining a longitudinal direction, a top surface and a bottom surface. The substrate has a plurality of conductor terminals arranged in a substantially linear relationship. A first support element is located below the bottom surface of the substrate and a second support element is located above the top surface of the substrate. The plurality of conductor terminals are positioned between the first and second support elements. The substrate may be a piezoelectric device having a piezoelectric layer arranged between first and second conductive layers. The plurality of conductor terminals may be arranged in a substantially linear relationship along a line about 80&#xb0; to about 100&#xb0; to the longitudinal direction of the substrate, and the longitudinal direction of the substrate being substantially perpendicular to the direction of rotation of the tire.
